Nobody would waste time identifying where all the 1 trillion species on planet Earth went to since they are literally everywhere. Some of them are so tiny you would want to step on them because they might get spread into even tinier pieces. However, some people would rather step on them in order to end their misery. There is no telling how long these microbial species will live as some could live as long as a human being while some would last just a few seconds. You can’t help but feel sorry for those species that won’t last long unless you believe in reincarnation. When you see a plant or an animal, you don’t really know how many microbial species is living inside it.
